To all whom it may concern: 7

Be it known that I, FRANK H. HAMPTON, a citizen of the United States ofAmerica, and a resident of Pullman, county of Cook, State of Illinois,have invented certain new and useful Improvements in Cushion Edges, ofwhich the following is a specification.

The main objects of this invention are to provide an improved form ofcushion edge adapted to form afirm sup ort for the edges of thecushioned surfaces of a spring cushion while at the same time beingsufficiently flexible to yield differently at different points when thepressure thereon is unequally distributed; to provide an improvedarrangement of the edge pad with respect to the spring structure; toprovide an improved form of fastening clip for connecting the edge whichclips may be fastened at either strai ht or curved edges of a cushionand may e made of,either wire or flat material; to provide an edge padand fastening means which require no special base to rest upon, but maybe fastened directly to the upper convolution of a coiled spring; and torovide an improved construction for one ion edge pads whereby the padwill return to its normal shape after distort-ion. These objects areaccomplished by the device shown in the accompanying drawings, in which-Figure l is a section, artly broken away,

odying this inveng. 2 is a section taken on the line 2-2 of Fig. 1 andillustrating the edge pad securing means as viewed from the bottom, theedge ad being also artly broken away to show .t e jointed, resi ientreinforcement of the core. Fig. 3 is a corresponding View showing amodified form of the fastening clip and the means for securin it to thes ring frame. Fig. 4 is a side e evation of the parts shown in Fig. 3,the edge pad and cushion bein shown in section, and the line 3-3indicating the plane from which Fig. 3 is viewed. Fig. 5 is a sectionaldetail indicating the method of folding and sewing the sheet ofcanvaswhich forms the casing of the edge pad.

In the form shown .in the drawings, the edge pad consists of a casing 1,re erably of canvas, filled with a stufiing 2 of felt, sawdust, hair, orother yielding material. The casing is preferably formed by folding asheet of canvas upon itself at 3, as shown in pad ,to the springstructure,

bent to form a part 12 which Fig. 5, and sewing the two parts togetherat e 4 along a line parallel with the fold 3 and spaced therefrom asuflicient distance to provide an edge pad of the desired diameter whenthe same is stuffed. The sheet of canvas is of suflicient width toprovide comparatively wide flaps 5 and 6.

The spring frame may be of any usual construction. In the form shown inFig. 1', the frame comprises a plurality of coiled springs 7 of theusual helicoidal shape mounted upon a base 8. The edge pad extendsaround theotop of the spring frame and is fastened to each of thesprings in the outer row by means of a clip 9. The clips 9 are securedto the upper convolution of the correspondin springs and are alsofastened to a border p ate 10 which extends along the edge of the frameand is riveted to each of the clips 9, thus serving to bind together theupper ends of the sprin s 7 and also to support the stuffin 11 of t ecushion adjacent to the edge pa The fastening cli s, in the form inwhich they are shown in igs. 1 and 2, ,consist of single strips of sheetmetal. Each strip is encircles the edge pad. At another place it is bentto form a hook 13, which engages the outer part of the upper convolutionof the spring and the inner end of the clip, and at its inner end it issplit to form the narrow Q'ues 14 which are wrapped around the w. f theupper convolution of the spring. The part 12 of the clip is of suchlength that its end will engage the seam t'of the casing and hold saldseam at a position close to the top of the spring frame when the flap 5is pulled tightly over the top of the edge pad and secured to the bottomframe 8.

In assembling a cushionof this form, the clips and border plate 10 arefirst fastened to the tops of the springs, the hooks l3 and tongues 14being at this time closed around the wire of the springs so as to firmlyhold the clips and border plate in position, the parts 12, however,being left in an open position,,as indicated by the dotted lines in Fig.1,-so as to permit the insertion of the edge pad. After the edge pad isinserted into position, the parts 12 are bent down to the position shownby full lines by means of a suitable tool. The flap 6 is laid along theupper surface of the frame, and the flap 12 is drawn over the top of theedge pad and tacked or otherwise secured to the bottom of the frame.After the padding 11 is placed in position, it is covered by a sheet offabric 15 which is sewed to the flap 5 at 16. This is covered by theouter covering of the cushion, not shown in the drawings.

In the modification shown in Figs. 3 and a, the fastening clip 17 isformed of wire in stead of sheet metal, and the hook-shaped bends 18serve to secure the border wire 19 to the upper convolutions of thespring. In this form the connection between the clip 17 and the springis reinforced by a second clip 20, and the clip 20 is riveted to theborder plate 10 between the two parts of the clip 17 When the clip isformed of wire, it is preferably doubled, as shown, the middle part 21of the wire being shaped so as to have a broad bearing alon the seam ofthe pad, (See Figs. 3 and 41% With the form of fastening means which isherein shown, the edge pad is securely held in position while being atthe same time free to yield under unequally distributed local pressurewhich deflects some of the springs 7 more than others. The edge pad is,however, so supported that it always returns to its normal position andmaintains the shape of the cushion. As the clips are widely spaced, theedge pad is free to bend between adjacent clips, and it may yield eitherhorizontally or vertically.

In order to insure that the parts of the pad always maintain perfectalinement with each other when not under strain, the core thereof isreinforced by a resilient inner core 22 of metal. This inner corepreferably comprises a series of sections or links hinged together, thelinks being of such length-and being so placed that their joints 23 areadjacent to the clips 9. Thus the edge pad is free to yield with thecushion springs under local pressure, but always assumes its normalshape when the pressure is removed. The links 22 are embedded in the padmaterial so that they do not come into direct contact with the casing ofthe pad. In the form shown, the links 22 are each formed from a singlepiece of resilient wire looped at each end to engage the adjacent links.
